RADIATOR-SUPPORT.

Specification of Letters Patent.

Patented Oct. 30, 1917.

Application filed March 29, 1916. Serial No. 87,520.

To all whom it may concern:

Be it known that 1, AUGUST KEHM, a citizen of the United States, and resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Radiator- Supports, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The inventionrelates to a wall bracket for supporting radiators of that type which have hitherto been usually supported by being provided with-abase or legs which stand upon the floor. The great importance now attached to the practice of avoiding the use of permanent obstructions of any kind upon the floors of rooms, particularly in hospitals, schools and the like, where cleanliness is essential, and the improved appearance obtained by constructing radiators without a base, render it desirable to provide a simple and effective means for supporting the radiators from the wall. The object of the invention is accordingly to provide a wall support for radiators of the type described which shall be of simple construction but effective in service and arranged to permit a convenient installation of the radiator in the required position.

In the accompanying drawings,

Fig. 2 is a front elevation of the parts shown in Fig. 1, a detail of the floor being shown in section, I

Fig. 3 is a detail central, vertical, sectional view of the improved radiator support, the bracket being partly shown in elevation,

Fig. 4 is similar to Fig. 1, but shows a modified form of construction, and

Fig. 5 is a detail perspective view showing the construction of some of the parts.

The invention is more particularly concerned with providing a support for radiators which comprise a plurality of upright loops, as 10 (Figs. 1 and 2), or 11 (Fig. 4-). These loops are arranged side by side with a suflicient intervening space 12 (Fig. 2) to permit of a free circulation of air about the loops and adjacent loops are connected at their lower ends by horizontal nipples, -as 13 or 14. Furthermore, each loop comprises a plurality of upright columns with openings, as 15 or 16, between adjacent columns throughout the greater portion of their length.

In carrying out the invention upright wall plates, as 17 or 18 are secured against the wall immediately in rear of the place where the radiator is to be supported. These wallplates will vary in length in accordance with the height of the loops, as 10 or 11, of the radiator, and the number of wall plates employed may vary with the length of the radiator, though two such plateswill usually be employed with radiators of ordinary length. In most instances, lag screws, as 19, 20 or 21, 22, will serve for securing the wall plates 17 or 18 against the wall. The radiators are primarily supported by bracket arms 23 or 24, one of 'which projects outwardly from 'each of the wall plates 17 or 18. These bracket arms are preferably of reduced width to permit of'their entering the space, as 12, between adjacent loops 10 or 11 of the radiator.

A stirrup 25 hangs from the outer end of the bracket arm 23 or 24 for receiving the corresponding nipple 13 or 14 of the radiator. In order that this stirrup may be fitted about the radiator nipple it is preferably made openable and is detachably connected with the corresponding bracket arm 23 or 24. As shown, the stirrup 25 is formed in two parts or halves 26, 27, and these parts are hingedly connected at their lower ends with a hinge pin or pivot 28. To facilitatethe detachable connection of the stirrup 25 with the bracket arm 23 or 24, the bracket arm is provided with a depending head 29 at its outer end. This head is of flaring shape to be received between the two parts 26, 27, of the stirrup 25, when in closed position, and each of the front and rear faces of the head 29 is formed with a socket 30 for receiving an instandin lug 32 which is provided at the upper en of the corresponding part 26 Preferably the axes of the sockets 30 are normal to the corresponding faces of the head 29. The two sockets 30 are therefore somewhat downwardly inclined and provide a firm support for the stirrup upon the bracket arm 23 or 24. If desired, the

' front and rear faces of the head 29 may also be grooved below the corresponding socket 30, as at 31, (Fig. 5) to prevent lateral dis- 27 of the stirrup.

placement of the stirrup. vWhen the parts 24 is preferably so connected with the corresponding wall plate 17 or 18 that it may be vertically adjusted. As shown, a connect ing plate 33 is provided upon each wall plate 17 and 18 for engagement with the corresponding bracket arm. This connecting plate may be secured in position upon the wall plate by one of the lag screws, as 19 or 22, employed for holding the wall plate against the wall. In that event the lag screw 19 or 22 passes through the upper end of the connecting plate 33 and lateral displacement of the connecting plate is prevented by the provision of a stud 34 at its lower end for'entering a socket 35 in the wall plate.

The connecting plate 33 further has a chambered body 36 fdr receiving the head 37 of a clamping bolt 38. To permit the use of the clamping bolt for attaching the bracket 23 or 24 to the connecting plate 33 throughout quite a range of vertical adjustment, the bolt opening 39 in the chambered body 36 of-the plate is vertically slotted.

en so constructed, the face 40 of the plate 33, at each side of the opening 39, is serrated for the engagement therewith of the serrated inner end 41 of the bracket 23 or 24 in any adjusted position.

In practice the radiator is readily installed, if it is initially supported at the required elevation upon jack screws- (not shown). One of the stirrups 25 is then fitted about the nipple 13 or 14 in front of each wall plate 17 or 18 and is engagedv with the corresponding bracket arm 23 or 24 by closing the ends of the stirrup upon the head 29, of the bracket arm with the projecting lugs 3.2 entered in the sockets 30. The bracket arm 23 or 24 is then brought to a suitable elevation for the engagement of'the bottom of the stirrup with the under side of the nipple 13 or 14, and firmly secured in adjusted position by tightening the corresponding.

clamping bolt 38. When this operation has been completed for each support with which the radiator is to be provided, the jack screws may be withdrawn from beneath the radiator.

Any convenient means may be employed for holding the radiators in upright position in the stirrups 25. If desired, a T- headed bolt 42 or 43 maybe employed for this purpose, the bolt being entered in the space between two adjacent loops 10 or 11 of the radiator when the T-head of the bolt is .in upright position. The bolt is then rotated to bring the arms of this T-head to horizontal position-in which case they serve to hold the radiator upright by entering the openings, as 15 or 16 in the radiator-loops at opposite sides of the bolt.

When the radiator is composed of short loops, as 11, (Fig. 4) the T-headed bolt, as 43, may-be supported by having threaded engagement with the outer end of the bracket, arm 24. When radiators with longer loops, as 11 (Figs. 1 and 2), are employed, the wall plate, as 17, preferably extends for a considerable distance above the bracket arm 23 and the T-headed bolt, as

42, is located at the level of the higher endv threaded socket 44, is mounted upon, the

wall plate 17 for receiving the stem of the bolt 42. As shown, the socket 44 is secured against the wall plate 17 by one of the lag screws, as 20, which also serves for holding the wall plate 17 against the wall. Under these circumstances rotation of the socket 44 about the lag screw 23 is prevented by providing the said socket with a stud 45 which enters an opening 46 in the wall plate 17 above the lag screw. It has been found convenient to extend the walls of the socket 44 forwardly for a considerable distance be yond the screw threaded portion, as 47, with which the threaded stem of the bolt 42 is to be engaged, as at 48 (Fig. This forwardly extended portion of the socket has a smooth interior surface and serves for initially' receiving the stem of the bolt 42. It follows that if the bolt 42 is released, upon being entered in the socket, before being engaged with the threaded portion 47, the extended portion 48 of the socket will prevent the bolt from falling to the floor.

The invention provides a radiator support which is quickly applied and which is substantially concealed when in use. F urthermore, the construction of the support is such that the vibrations of the radiator are not communicated to the attaching bolts. Loos ening of the support in use is thereby effectively avoided.
